Hi,

I'm experiencing a long (around 20 sec) delay from the moment
u-boot-1.3.4 passes control to linux and until the first kernel  
message
appears on console.

I saw somewhat similar behaviour on 83xx target, the cause was
that my .config file contained bogus UDBG_RTAS_CONSOLE=y symbol
(or was it PPC_EARLY_DEBUG_RTAS_PANEL=y? Or HVC_UDBG=y? I don't
quite remember).

Obviously, on 83xx we don't have RTAS or HVC stuff, but kernel
didn't oops or hang completely, it was busy with executing various
delays in those drivers and then just continued to load.

Why are these drivers even doing anything on 83xx?  Seems like they need 
something to bind against or some detection of "HW".

Early console/UDBG is known to cause problems if enabled on
inappropriate hardware. They start working very early, so it's hard
for them to do the hw detection (no device tree yet, I presume).
